To be fair I only started looking since weekend - our subscription to Owl Intuition (Network Owl, alternative to Smappee) expired in March as did the network connection to the monitor so I’ve weekly figures from 2016-2018 but no daily/hourly.

Our 2.75 kWh array generated 8.7 kWh yesterday (Monday)

Meanwhile we imported 13 kWh to manage our 21 kWh usage!

What does your house consumption idle at? Ours idles at 1.6 kWh which I think is the problem. Solar rarely exceeds it.
